When 'commercial considerations' are often emphasised in both simulator and line operations and company manuals rather than regulatory documents are more readily recalled than regulatory limits, there is a problem. This is apparent in most airlines, not just those north of Australia.
When 'management' set the regulatory limit as a KPI target, be it minimum rest period or maximum duty time or where 'efficiency' relies on pilots accepting to exceed maximum TOD there is a problem. Where 'over nighting' in a hotel due TOD limits results in a loss of income (hence most push on) the system is broken. CASA are as duplicitous as airline management, safe in their beds, with teams of lawyers protecting the company and the institution.
It isn't complacency that is the problem, the normalisation of deviance has been a result of regulators looking the other way, all in the interest of 'commercial viability' Eventually pilots notice and they focus on the commercial too. After all they usually have big debt to service.
